(01; 91-12) This invention relates, as indicated, to a bead new machine for applying a beador band of enameling machine and more specifically to a enamel slip to the lip of a piece of Ware.

machine for applying a band of enamel slip to Referring nowmore specifically to the drawthe bead, flange, or lip of either the usual subing, the apparatus illustrated is a preferred emstantially circular enamel ware orware with Well bodiment comprising a rotatable shaft 1 driven rounded corners by a pulley 2 and'carrying an enamel wheel 3,

It has long been customary to ornament the lip which dips into thetank d'containing the enamel or head of enamel ware utensils and the like slip to be used in heading the ware. v Said shaft with a band of colored enamel in order to give I also carries a rubber-tired wheel 23 of the a more attractive and finished appearance to the same diameter as the enamel wheel 3'. The final product. In the past this band or stripe, rotatably mounted hollow shaft 5 is supported generally termed the head in the enamel inin its housing 5 above said shaft l by the arms dustry, has been applied entirely by hand, using 24 and pivotally mounted on a stationary bar the fingers or a brush.

The machine of Figs. 1 and 2 may be constructed so that upon lowering the upper shaft 5' the wheel 28 will make contact with the wheel 23 before the ware touches the enamel wheel, thus causing the ware to be rotating when it contacts the enamel wheel. This may be accomplished by providing means for tipping shaft 5" slightly.

The slip is the usual enamel slip and may be made up with water or any other suitable suspension medium. The angle of contact and the 2 type of enamel wheel together with the viscosity features stated in any of the following claims, or
